Future before the past

There's a serial killer at large in Los Angeles, California. He's been terrorizing the city for decades and ridiculed the local police thus they are under heavy pressure to capture the sadistic killer. A team of old and new detectives is frustrated as fuck. It's been a little quiet in the serial killer cinema as of late, The Little Things is something, but after a decent start it barely goes nowhere and the story doesn't really have an ending. Surprisingly, Rami Malek - Hollywood's new favourite pet - looks like a rookie in the company of the heavy-weights Denzel Washington, Chris Bauer, Jared Leto and Terry Kinney.
